[back in black]

Hey now, recently joined and wanted to thank all for a variety of fix it tips, especially the son of a gun treatment on the blk vert top... real kindy turnout, power pleased, joy. Would like to ask if anyone has thoughts with a sagging rear bumber cover? 91 gt 5.0 vert? Cant seem to alleviate sag, right in the middle. %&^$#
Kindly, Back in Black 91 gt vert blkx3 not many mods yet, though a real kick to pull on. Thanks again
